This CS0-003 practice question tests your understanding of security operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Refer to the exhibit. The snippet is from a Windows Security log showing event ID 4688 (Process Creation). Which of the following actions should the analyst take first?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Investigate the creator process
The analyst should first investigate the creator process (parent process) because the suspicious svchost.exe spawned from rundll32.exe in a temp directory indicates a classic LOLBins (Living Off the Land Binaries) attack. Event ID 4688 logs the parent process PID (0x1234) and the child process; tracing the parent reveals the initial compromise vector, such as a malicious script or document that invoked rundll32.exe to execute the payload.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Kill the process with PID 0x1234
Why it's wrong here
Killing the process could destroy volatile evidence before analysis.
✓
Investigate the creator process
Why this is correct
The creator process is running from a non-standard location (Temp folder), indicating compromise.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Quarantine the file C:\Users\admin\AppData\Local\Temp\svchost.exe
Why it's wrong here
Quarantining is premature without first investigating the process's behavior.
✗
Disable rundll32.exe on the system
Why it's wrong here
Disabling rundll32 would break legitimate system functionality.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the misconception that the immediate child process (svchost.exe) is the primary threat, but the trap is that the parent process (rundll32.exe) holds the key to understanding the attack chain and should be investigated first.
Detailed technical explanation
How to think about this question
Event ID 4688 includes the Creator Process Name and Creator Process ID (PID), which in this case shows rundll32.exe (PID 0x1234) spawning svchost.exe from a temp folder. Under the hood, Windows uses the Token and CommandLine fields to track process ancestry; legitimate svchost.exe runs from C:\Windows\System32, so a temp path is a red flag. In real-world attacks, threat actors use rundll32.exe to execute malicious DLLs via JavaScript or VBScript (e.g., in phishing emails), making parent process investigation critical for identifying the initial access vector.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
